5301.22
Effect of agreement with a guardian.

As used in this section,
"incompetent
person" means a person who is so mentally impaired, as a result of a mental or physical illness or
disability, as a result of an intellectual disability, or as a
result of chronic substance abuse, that the person is incapable of taking
proper care of the person's self or property or fails to provide for the
person's family or other persons for whom the person is charged by law to
provide.

No agreement described in
section 5301.21 of the Revised Code
shall be executed by a minor or incompetent person, but it may be executed and
delivered for record, on such a person's behalf, by the person's guardian. When
executed, acknowledged, delivered for record, and recorded, such agreement
shall be as effectual against such minor or incompetent person, as if the
person had been under no disability, and had performed such acts personally. An
owner, not under any of such disabilities, may perform all such acts by an
attorney in fact. The power of such attorney must be in writing and first
recorded in the county recorder's office.
